If we look at current conditions in which our natural resources in the form of crude oil are increasingly depleted, we must start thinking about another alternative that can substitute petroleum to run the car. In addition to oil reserves are increasingly depleted, we must also start thinking about the pollution it causes. So that is needed now is environmentally friendly cars that will be able to reduce the pollution on earth.One alternative that is currently being developed is a fuel gas. Liquefied petroleum gas (LPG) is a liquid gas that is on earth, whose existence is often encountered to light gas stoves. Its flammable and more environmentally friendly than the current car fuel alternatives makes LPG fuel environmentally friendly cars.Actually not too hard to use LPG as automotive fuel, many manufacturers are doing research about it. Just doing a little modification of the car especially on the engine.As performed by Italian car manufacturer Alfa Romeo, manufacturer of luxury cars combine a gasoline engine with gas-fueled engines (LPG) capable of speeding. Because the combustion process that occurs with LPG fuel is also perfect so that the power generated will be maximum.Inside the trunk are sized 39 liter gas cylinders and with a combination of gasoline with LPG, the Alfa Romeo Mito go as far as 1,200 km. Although practically environmentally friendly cars, Mito can still dibesut to 120 horsepower and it took 8.8 to reach 0100 km / hour.As in many other countries, environmentally friendly cars always get special attention from the government so they give tax breaks, cut 4500 pounds, or USD 67.5 million. Mito is priced 13,900 LPG-powered or around Rp 220 million.In Indonesia there was already a car repair shop who tried to use LPG fuel for stoves commonly used as automotive fuel. A clear benefit from the use of LPG fuel is more than the use of gasoline or diesel fuel are becoming increasingly depleted, besides the issue of global warming one cause of the fumes.
